Junk Science Blogs: 4 Signs You May Be Unknowingly Following One

by The Health Sciences Academy — Get free science updates here.

The internet is growing uncontrollably. Ultra-fast information transfer is happening across this world via a network of communication satellites.

Nearly everything has changed with the onset of internet, and over the past years we’ve seen vast improvements in technology, communication and virtual entertainment. All thanks to the internet.

The internet has also been pivotal in introducing improvements for education purposes; one can access online courses, supplemental information for a subject of their choice, and expert health and nutrition advice. The internet has opened up a substantial amount of knowledge to a wide audience around the globe.

But it can also be a minefield

The era of information failure

Einstein said: “A little knowledge is a dangerous thing. So is a lot.”

Information failure can happen when the participants don’t have perfect knowledge, or when one set of participants know more than the others causing information asymmetry.

An information failure is often detrimental; causing confusion and uncertainty. It can affect a lot of subject areas, particularly health and nutrition.

According to recent reports:

  • 80% of the population from developed countries (like the UK, the US, Germany, Australia, Japan, Canada, France, etc.) use the internet.
  • 70% to 80% of us use the internet to search for health information online (Tonksaker, 2014 , HINTS, Pew Internet and the European Commission).

These are really staggering stats.

But they come at a high price: we now have an increased risk of damage caused by information failure. For all we know, there could be millions of bloggers spreading wrong advice about health and nutrition… putting their followers’ health at risk.

The harm of misinformation

With so many self-declared “evidence-based” websites floating around, what (and who) should you believe – or not?

How do you know you are reading quality-verified information? Who can you trust for accurate data suited to your needs? Who filters the junk from the science?

These are a few questions you should be asking yourself constantly.

I personally have a very rigorous vetting process and spend a lot of time and resources to access, validate, and distil top-quality material.

The first step in this process is to identify whether I’m reading bad science or not. And I would like to share with you some of the red-flags I normally watch out for.

Here is a list of four common slip-ups made by health blogs, even when they proclaim to be “science-based”:

1. They oversimplify information.

Our world is full of big and unstructured data.

However, bigger doesn’t always mean better. The value of data is determined by the quality of its analysis.

While simplification of the conclusion is necessary to target a wider audience, a balance must be maintained so as not to distort it.

Here’s one simple example of causal oversimplification:

“When the team won the last game, the coach said his team had pizza before the game… surely the team won because of the pizza they had, therefore one must have pizza before the game to win the game”.

Can you see the weird logic?

Two unrelated topics have been linked and used as evidence to back up a made-up conclusion.

Many health bloggers intentionally link unrelated data to mislead their audience, giving them a false sense of satisfaction.

Example of a non-sequitur (by niyamaklogic)

Now, have a look at the image to the left.

Two is a number. One is a number. Therefore, two equals one.

Quite convincing, isn’t it?

That’s the oversimplification formula that many health bloggers and journalists use…

It’s called “non-sequitur”. A kind of fabricated logic you should always watch out for!

Let me give you another example.

In news, the Daily Mail claimed that “Eating fruit could make you MORE hungry because the sugar in it triggers cravings”.

But the cited study didn’t involve fruits at all. Then how did the journalist conclude that?

Easy. By using the oversimplification formula! Somewhere along the following:

  • A fructose drink increased cravings (study).
  • Fruits contain fructose (common knowledge).
  • Therefore, fruits increase cravings (Daily Mail).

Can this be used as evidence that eating fruit makes you hungrier? No.

This information has been pulled out of context.

And context matters! In this case, drinking fructose is very different from eating whole fruits, where the fibre slows down the release of fructose into the bloodstream. Fruits also have a high water content and take longer to digest, so fructose is not instantly absorbed.

Now that you are aware of the “causal oversimplification” tactic, see if you can spot it in the blogs you follow (and please let us know when you do!).

2. They “spin” the findings.

Most health blogs miss out on the critical findings of a study.

Image source: shirtofun.com


They opportunistically cherry-pick a few words from a study abstract to support an argument, without ever reading the full study.

Recycling words from a study abstract and using that as “evidence” carries several problems.

Particularly the problem of “spinning”.

It’s been reported that 41% of clinical-study abstracts are distorted by the scientists themselves with an attractive “spin” to make the key findings news-worthy  (Yavchitz et al., 2012; Sumner et al., 2016; Dumas-Mallet et al., 2017).

What happens then?

These “spinned” abstracts are spread by health bloggers and journalists who, in general, don’t bother to read the original full study.

For this reason, I never “buy into” an abstract. Unless I read, absorb, and understand the full scientific paper back to back, I won’t put it forward or even show it to you.

The point is that you must be vigilant about the way some health websites are trying to convince you, often by randomly plastering links to PubMed abstracts on a page in order to create an illusion of “evidence”, without fully understanding:

  • the study type,
  • the research methods,
  • the context in which it was carried out,
  • why it might contradict previous findings, and
  • whether it was a one-hit-wonder with irreproducible results.

This shows how anyone can be misled by bloggers who skip crucial information and pick isolated conclusions from the scientific literature, concealing the full picture.

Sadly, health myths are born this way many of which we debunk in our Science Reports!

3. They disseminate junk science.

Vetting a study for scientific integrity before citing it is crucial. Why?

Because sometimes science can be falsified by the medics and scientists themselves.

I know, that’s a shocker.

It is very important to find out if the results can be reproduced, if it was published in a peer-reviewed journal, and how many test subjects were used.

Image source: briandeer.com

Notably, a 1998 study by surgeon Andrew Wakefield and his colleagues is believed to be responsible for the modern anti-vaccine movement.

They observed that 8 of the 12 children developed their first symptoms of autism shortly after they received the MMR (measles, mumps, and rubella) vaccine.

This correlation was weak and although other scientists denounced this claim, several media outlets issued dramatic headlines linking MMR to autism.

Numerous follow-up studies failed to replicate this study and couldn’t find evidence linking vaccines to autism.

Furthermore, in 2004, journalist Brian Deer in his report revealed that Wakefield had been hired by a lawyer to find evidence against the vaccine to support a lawsuit and had falsified the data in the 1998 study.

This study was retracted in 2010 and Wakefield was stripped off his medical licenses.

Despite the scandal, some bloggers keep citing the retracted study!

More recently, a German journalist fabricated a scientific study to prove how easy it is to fool the media with junk science.

He used the alias ‘Johannes Bohannon’, but his name is John. He recruited real subjects, performed a real experiment, and published his findings in a real scientific journal called the International Archives of Medicine, which used to be run by BioMedCentral.

But the truth is that he somewhat “manipulated” the study data to make us believe that eating chocolate daily accelerates weight loss.

The result?

Image source: Daily Express

Image source: Daily Express

Shape Magazine, the Daily MailDaily Express, Daily Star, many other media outlets and health blogs released the “magical” news: get slimmer with chocolate!

In his fascinating article, John reveals how he duped millions with his fake chocolate findings.

So, how do you know if the data in a study has been manipulated or not?

Well, that’s why we are here: the team and I vet studies for scientific integrity and ensure that everything we teach you in our Science Reports and in our courses is based on a proper interpretation of the science.

4. They create a psychological nocebo effect.

Several health websites exert the power of the ‘nocebo effect’ upon their readers’ minds.

In a prank gone horribly wrong, a group of medical students picked on a much-disliked assistant and caught him unaware. They blindfolded him and bowed his head onto the chopping block; they announced that they would decapitate him, and dropped a wet cloth on his neck. Convinced that it was a steel blade, the man died on the spot.

This example has been cited in Dr Benson’s work in 1997 and just goes on to show our brain power and how dangerous these beliefs can be.

Image source: davidmallenmd.blogspot.co.uk

Many health sites terrorise their readers with pretty scary headlines and give out selective information about a study, or don’t talk about the biological evidence.

This increases the scientific gap and can lead to the creation of dangerous beliefs in your head.

Believing that a certain food will harm you can be as powerful (if not more) than the negative effects of the food itself. We explain how this can happen in our Science Report Gluten: A psychological nocebo?

Sometimes you may be better off by NOT allowing this kind of information to play with your mind, even if subconsciously.


So many health bloggers underestimate their readers’ intelligence.

H.L. Mencken, a journalist and a scholar of American English, stated:

“No one in this world, so far as I know — and I have searched the records for years, and employed agents to help me — has ever lost money by underestimating the intelligence of the great masses of the plain people. Nor has anyone ever lost public office thereby”.

Looking at today’s ‘blogsphere’, Mencken’s opinion might be more relevant than ever!

Although knowledge can empower us, I’m worried about the quality and quantity of information out there, how people use it, and how it can affect them.

More harm can be done by accessing false or misrepresented information, and using such information to make a decision.

Online stories are pulled out of context, sensationalised, or fabricated… just to get your attention.

You must be critical of popular blogs, particularly when you identify any of the red-flags we discussed:

  • Are they using the oversimplification formula to fabricate a false logic?
  • Could what you read be a complete misinterpretation of the scientific literature?
  • Are they using junk studies, or taking partial information from abstracts, without reading and validating the full study?
  • Are they applying scare-tactics and planting an unnecessary nocebo effect in your mind?

If you spotted any of the above in the blogs that you follow, please tell us in the comments below the general public has the right to know!

    another good article Alex. I like to read more about the science rather than getting caught in what the so-called ‘glossy experts’ say. Glossy experts is the term I refer to people who may be of great influence, and may have lost weight or followed a plan and share it with the public, not fully understanding the science. You so right about how sometimes people don’t get the full picture. You get people saying that they should not eat ‘carbs’, they may not realise that they need it to function for example if they are doing strenuous exercise. I remember having a discussion about someone who worked at a qym and they had some customers fainting as they tried to eliminate or carbs from their diet.

      The problem with gym-based low carb diets is that they should also be eating veg. A ketogenic diet is used officially with epilepsy, normally children, and there’s been research suggesting positive for brain injury patients also. But it needs to be done properly. As for non-low carb diets of a similar nature you get carbs from fruit and veg! But I’m always a little suspicious about non-medical uses of ketosis, esp in a gym setting. As for the example above, I suspect that the person knew nothing about low carb diets, the need for good fats, and to watch for low blood pressure, and so fainted as a result

    Very informative – thank you very much!!
    Just one comment though – I’m curious – your article says “our…is based on proven research”
    As far as I am aware – you can’t say “proven research” because all science is a testing of theories and hypotheses – you can only say evidence “suggests…”

    Would you agree?

    • Hi Shona – Nice to hear! Proven research, theories and hypotheses are 3 very different things. Proven research is, for example, when the reproducibility of the study results is tested (and high), or when there’s scientific consensus, or when the research is well-established, amongst many other factors. You can see how we make sense of the scientific literature in our Science Reports Premium: https://thehealthsciencesacademy.org/science-reports-premium-subscription It’s fun!

        Hi Maria
        Thanks for your reply :-)
        I understand the difference between research, theory and hypothesis testing.
        Perhaps I am looking at it more philosophically – technically speaking only mathematics can be proven in a theoretical world. Because theoretical testing is usually in a laboratory or some other ‘unreal’ world scenario, not all theory, even though perhaps supported by large weight of evidence, may not always translate perfectly into the real world for all real world situations.
        Hope that makes sense. :-)

        • Shona, haha yes, “philosophy of scientific knowledge” is a fun subject matter, particularly for logicians. Biological research on the other hand has its own set of rules and methods to ensure consistency, and that’s our main focus as you know. Thanks for commenting, nice to have you around :-)

    Wherever large financial interests are involved, then truth takes a back seat. This applies to banks, politics, government, pharmaceutical companies, medicine, agriculture, the food industry, research organisations, sport and even charity and aid organisations. We really can’t know for certain where the truth lies, unless you hear from credible whistle blowers who can document their evidence. In our area of interest books such as Drug Muggers and Pharmagheddon give us some expert insights into horrendous practices on a massive scale. In my mind statins serve a financial purpose not a health one and the story about cholesterol is distorted to fit the case. The way general medicine is taught and structured is aimed at treating symptoms of chronic disease and not looking for a cure by addressing the underlying causes.

    We are programmed to survive as individuals rather than as communities, when it comes to the bottom line. This behaviour extends into the way we conduct our business in many situations. Civilization is a thin veneer that covers over some pretty nasty instincts. It is sad to see how quickly we can adapt basic tribal behaviours and set about killing each other so readily when roused in a particular way. I hope that is not too depressing for you to read. All we can do is moderate our individual behaviour.

    Good article. It is true, the internet is full of this false or many times half true half lie stories. For example the validity of supplements and later another one indicating that supplements create cancer, or coffee is good and a week later coffee is very bad, and so on. Unfortunately, not always is possible to track the original source or its time consuming, specially if is not part of your job to do that. Many times when there is a scientific article, you have to pay per article and is not always cheap or affordable unless you are a member of a faculty or full-time graduate student. Anyway, I will let you know when I find some kind of bad/junk science.

    Great article, Alex. It is scary how true is all you wrote about “junk science”. It takes a lot more time, energy and judgement to sip through, analyze and decide what is valid information. It is so unfortunate though that so many people fall victims to it, even highly educated professionals. When money is the most powerful tool in pretty much anything and everything, it manipulates the “science” so often making it so much harder for majority of the people to discern the real science from the junk.

    I’ve been involved in engineering for many years so I must watch out for this kind of science. The SELECT study was a study on Vitamin E and selenium and cancer however on the first blood test at the beginning of the study they measured several blood parameters including omega 3’s. This was the only measure of plasma omega 3’s. At the end of the study the researchers noticed a correlation between that one test and prostate cancer levels and concluded that omega 3’s were a cancer risk factor. Absurd. Your omega 3 level on one day in your life cannot tell you anything about your health. This wasn’t blog but a research study with a spin to make news or worse.

    Eye-opening, Alex. Enjoyed this so much.

    I’m adding a new term to my vocabulary… NON-SEQUITUR!

    I stopped following Mercola a long time ago, they use non-sequiturs a lot, like in the microwave scare and the Russian ban. Really? The conclusion is spot on, no one has lost money by underestimating the intelligence of the masses. I think Mercola makes a lot of money with his flashy ads all over the site which makes it even more suspicious.

    Food Babe over-promotes her book but she has no training in human metabolism, toxicology, or environmental science. I lost faith when she said “There is just no acceptable level of any chemical to ingest, ever.” Water is a chemical. Vitamin A is a chemical.

    I also believe it is very dangerous to install nocebos in people’s minds as you say. It makes you very paranoid.

    Thanks Alex – A good article and certainly makes you think. I was about to have my daughter vaccinated with the MMR vaccine when the news broke about the dangers and “links” to autism. However, I had measles as a child and was lucky it caused no lasting damage, but I know of others who were badly affected by it. Also, the dangers to an unborn child if the mother catches rubella are also significant, and so for me it was a no-brainer. There were plenty of other mums who decided not to vaccinate though and I wonder if the retraction of Wakefield’s “findings” was publicised sufficiently well for mums to change their minds

    Enjoyed the article as always. The responses were interesting as well. If we understand the idea of blogging, which is no more than giving our opinion about certain things to the public or readers, it will help because testing is a total different subject. It involves groups of people, specific requirements, age, sex, even demographics and more. Also, we must understand that the quantity of participants and the time frame the study was conducted will give us evidence of its findings. Yes, it would be so great if most bloggers would take this in consideration and for instants post the correct data, however, we the readers should research the info mentioned. Now, that’s being said, you may find studies that show all of the details, but they are financed by companies to show a specific outcome. Just to give you something to think, does anybody believes that the FDA would change the food pyramid showing that animal products are negative for your system- increase the risk of cancer, increase inflammation, increase resistance for certain antibiotics, etc? That would mean that anybody on the panel that also is involved with the beef industry, chicken industry and so on, would be in a trick. But it’s us, the reader’s responsibility to find out who is involved in a study, who did the actual research, and how can the outcome help us to make better decisions on our food intake.

    I agree with you that we must make sure that our sources are reliable and that we are citing and teaching factual material and I believe that we must keep an open mind to new and alternative findings. I’ve come to distrust the CDC and FDA here in the USA because they are so tightly enmeshed with big business having embraced profit over the health and well being of the people. It’s easy to not report findings or to manipulate them in favor of a desired outcome, especially when money is involved. I appreciate alternative voices as well as mainstream voices and remain curious with all. The vaccine debate is an important one and should be examined from all angles possible. Someone with a family history of autoimmune or immune compromise, genetic defects such as a MFTHR defect would be at risk with the toxicity of vaccines. SB277 here in California has now eliminated parental rights to deny vaccination and only leaves medical excuses to avoid them, and I’ve never had a doctor suggest a genetic test on my babies so how would one know if they would have a tragic consequence? So, yes, check references and sources of information and be very curious and open minded to all sources. Science is a field of learning and we must continue learning without thinking we already know it all just because a governing body says so.

Back in 2015, around 15 naturopaths were assassinated in US because they spread the information of the vaccines carrying cancer gens, to increase the cancer rate in the population.

    Hi again,
    I want to ask one question about “Brown sugar”, an issue which has bothered me for some times. I was researching on the net about the benefits of brown sugar. Some doctors claim that brown sugar is not much different than the white sugar, because the nutritional value of the amount of the molasses is almost insignificant. What is your opinion on this issue, and is it significant if the brown sugar is organic or not.It is still 95% sucrose.

    • Hi Eli – as you do your research on brown sugar, you’ll want to consider the concept of “inter-individual variability” (i.e. genetics/tolerance, personal biochemistry, current diet, health status, nutrient deficiencies, etc.), reason why general findings aren’t always applicable. Similarly, you’ll want to look at the source of the product you’re researching, e.g. soil quality, soil contaminants, producers’ methods, etc.

What do we do as informed individuals and professionals to weed out this proliferation of misinformation? How does one in social setting , say a party stop even this conversation of misinformation being proliferated? Indeed health and nutrition are topics that are constantly being “addressed” in almost every social setting.

      Hi Sam, I’m not a researcher or blogger (yet!), simply a lifelong student. I have encountered the problem you mention in social settings and on social media, in reference to misinformation proliferation. It is a fine line to maintain a sense of decorum with certain individuals in this situation. When addressing a reasonable person, one may simply point out there are existing studies with reproducible results which counter the misinformation. With an uninformed zealot, especially those with a stubborn streak, I find it often best to google the subject matter on my smartphone and share the link to a peer-reviewed paper when available. .edu sites are my second line of defense. Hope this helps you avoid some of those nasty, fruitless debates.

    I recently read Dr Mercola’s book ‘effortless healing’ which was an interesting read but I did feel scared reading it so haven’t been onto his website. I’m glad I read this, i won’t waste more time with Mercola and will be reviewing who I follow right away!

    Great article, and super important. I haven’t read the gluten, a psychological nocebo article yet but, I certainly plan to. I don’t have Celiac but, I do break out in eczema when I eat gluten containing grains. I have done the elimination diet multiple times to ensure that this was in fact the culprit. I have read both sides of the data, I am also a firm believer in listening to one’s own body as what may be good for one may not bee good for another, something you teach in your Nutritional Therapy course. I also recognize that scientific studies require funding, need to show some sort of economic profitability outcome (how can this study lead us to reduce economic loss or increase economic gain?), and the issue of the study has to be pressing enough to warrant the funding (only about 1% of the population is celiac so why study gluten?). That being said, just because there is no science, yet, doesn’t mean there won’t be. If gluten is a psychological nocebo, shouldn’t I have the power to mindfully eliminate my eczema just by believing that the data is false and that I am okay with gluten? If our minds are powerful enough to cure or kill, maybe that’s what we need to spend money researching. ;-)

      Crystal, this is of topic but in response to your point regarding the research about studying placebo/nocebo, there is a program about it. You can find more information on Dr Joe Dispenza.
      Because it is not only food and vitamins, is your state of mind and how you cope with your personal situation that also helps your health.

    Caveat emptor. It’s not just blogs. My twitter feed has promoted scams quite often. There is no such thing as miracle cure that no other scientists know about. Testimonials aren’t a substitute for verifiable science. For example there is no way to verfiy whether testimonials are made up or the people even exist. These organizations play on desperate people’s hopes. Dr. Mecola and Dr. Oz are two such entities. Popularity isn’t the same as being truthful. If it sounds too good to be true it probably is.

    Thanks for the article, the more I read, the more skeptical I become. This all started when I asked my dermatologist how she felt about the huge influence the Environmental Working Group was having on sunscreen sales, etc. She said the biggest factor for protection was how much you applied, and how often, and said that EWG to her knowledge employed no dermatologists, and their studies were flawed. So, I checked out their Board of Directors. Oh, wow, eye opener! Campaigners, marketing specialists, attorneys! Now I always go straight to the Board list as well as the financial page to see what makes a particular website tick.

    Thanks for raising awareness. This week I spotted a made up pseudo scientific logic by the institute for integrative nutrition blog / they wrote that whether you need to take omega 3 supplements or not depends on your ancestry but the linked study wasn’t about *supplements* at all ! appalling ..how research is distorted to gain believers and advance commercial interests is a disgrace. as I read the comments in here I can see that others also notice these things but it worries me that we are just a small minority.

    Very few really understand exactly what the body needs to function at its best – one has to be very careful who you put your faith in.
    Media loves “shocking” articles to attract readers and at the end of the day, those who take them seriously, without seeking further clarification, are not smart.

    I only enrolled today, (07-04-16) so haven’t started my course yet. But the article in question really gave me confidence in the thorough way the “Science Academy” sifts through all material before allowing it to be shared in their studies. I feel I can look into things more wisely now!

    If one looks hard enough – and one doesn’t have to look that hard – it is possible to find the cure for a certain disease according to one person is the cause according to another! If I came up with the most outlandish lie and sent it to a bunch of friends they may forward it to a bunch of friends who forward it to a bunch of friends until someone sends it back to me because I am one of their bunch of friends. Suddenly thousands of people believe the lie ‘because they read it on the internet’…

    I am ill and though doctors train for seven years, I won’t bother them: I shall look it up on the internet and believe what some spotty 14-year-old posted because he sounded authoritative! No, go and see a bloody doctor!

    I was a vegan for many years. I am not a vegan now, but still do not consume any dairy products.
    I still follow a vegan forum, and the information people write is so misleading it is at times quite dangerous. I will give you one example: “New vegans do not have to worry about the vitamin B12, because our bodies store B12 for up to 4 years.”
    Thanks to the scientific information I am studying with the course I am doing, I will be able to answer some of these problems.
    Thank you for all I am learning with THSA.

    Elizabeth, have you ever had raw cocoa? Munched on the actual bean? It is VERY bitter. I really like dark/bitter chocolate now – milk is far too sweet – but anything above 75% gets a bit unpalatable. I have some 95% dark chocolate, which should only ever be used for cooking!

    Reply Reply August 23, 2016

    For me it’s not so much the chocolate, as the milk… Milk chocolate is far too sweet for me since my life-changing accident. Dark (bitter) chocolate does not taste that bitter to me, though anything greater than about 72% is a bit too dark for me. Dark chocolate in the lower 70s is a delight though!

    Like fat, without sugar, raw cocoa is not nice at all, but mixed with sugar one gets biscuits, muffins, doughnuts, pretzels, cakes and of course chocolate!

    An amazing article. It makes sense. A lot of nutrition articles out there that are abstracted double or thrice. You can feel that pieces of information (or facts) was skimmed from different sources, but can’t tell. Further, you can find the same article “literally” but in a different organization on other sites as they share it but change its order, language, phrasing, etc. The trick/ experiment of the German journalists is really unbelievable and deeply funny. OMG, I can’t believe that; I am so astonished! You know something, just few lines starting reading your article I decided to throw out all the emails I have and try to format my mind for real healthy information. I open my eyes and ears wide for what you are going to say and share; though frankly I said to myself, why not them too!!?? I hope I can develop the sense to hunt false information, by your help and guidance of-course.
    Thanks for sharing this information with us.

    Thank you.
    Its very difficult tin todays world as we are all living such hectic, almost chaotic lifestyles and finding the time to sit down and take a breath is almost impossible for so many, especially those busy mums and dads, its hectic.
    So finding the time to cut through all the BS by allocating yourself time to garner the truth in the science of nutrition, exercise science, anatomy, physiology, genetics, psychology (need i go on) would quite honestly require a full time work load. So its now so unrealistic to be able to find sound, evidence based information that has no hidden agenda outside of truth and legacy.
    As a Consultant Nutritionist and Exercise Scientist i have a moral compass that drives me and thus allows me to follow my sound ethics to only ever provide information that allows my clients to become greater versions of them without harming themselves physically, mentally or emotionally along their lifestyle behaviour changing journey.
    I love my work and with some 25 plus years doing it i would love to say im doing y darndest to leave a legacy that only adds value to this magical world we all call home.

    I remember a lot of media interest in the 70s reporting that people cannot absorb vitamins by ingesting vitamin tablets. I’ve searched for articles to examine this issue but there seems to be a general assumption that viitamin supplements work. Does anyone have any information about this please?

    • Hi Lizzie! Yes, there’s a lot more science now on this. Different supplemental nutrients are absorbed in different ways and at different rates. Rates of absorption are largely influenced by several factors, so for example how much or how little of each supplemental nutrient is absorbed depends on things such as intake timing, dosing, combination with other nutrients that aid better absorption (or that impair it!), whether you take it with food or not (this varies, with some being better absorbed with food and others without food) and so on. There’s so much science on it now that we have a full certification on its own dedicated to it, take a look at the curriculum here: https://thehealthsciencesacademy.org/cpd-accredited-online-course-dietary-supplements/ Enjoy!

    Here, take a look at this one. It talks about “biophotons” being a type of “bioinformation” which leads to the feelings of wellbeing one gets when eating natural foods (which are destroyed with so-called “dangerous” microwave radiation.)

    I’d love to hear a detailed rebuttal to this one.

    • Thanks, Malakai! Yes, that’s a great example of pseudo-science… When people make big claims like that but without giving you any scientific references or without showing you studies from peer-reviewed journals to back those claims, then your “junk science alarm” should be immediately activated! Quotes from fake experts, anecdotal connections, or even citing court cases, are never evidence in the field of nutrition science… There’s a rigor that always needs to be applied to prove anything in this field. Our scientists looked at microwaves/food, see here: Is Microwave Radiation Harmful? https://thehealthsciencesacademy.org/health-tips/microwave-radiation/ Also, to date, there’s no research that ever proved the biophotons/food theory whatsoever… more here: Raw or Cooked Food: Which Option Grants More Nutrients? https://thehealthsciencesacademy.org/health-tips/raw-or-cooked-food/ I hope this helps!

This creates a knowledge Gap for an ever increasing health problem like obesity. As general practitioners in the developing world we are called upon to attain to these patient and unfortunately the internet tends to be our only source of information. since it is full of so much unverified information on the management of weight, this is always a frustrating adventure.

    • Caro – we love to hear you’ve enjoyed this! Interestingly, we were just talking about this within our Certified Nutrition Professionals Group at The Health Sciences Academy. Alex Ruani our research director made a very interesting remark. She said that we may become an encyclopedia of scientific knowledge but it can drive clients (in your case readers) away if all we do is try to show off how much we know without keeping them in mind and having a true interest in helping THEM… In other words, people don’t care how much you know until they know how much you care :-)
